Hemoglobin and its function in the body

Everyone knows that if you lowered hemoglobin is bad, it means that the person suffers from anaemia or anemia. Otherwise, the hemoglobin level above normal – good or bad? Is it worth the person concerned if he has elevated hemoglobin? Turns out it’s not that simple: you need to be examined and only then can you tell if you have a medical condition or is one option.

High hemoglobin-bad or good?

Hemoglobin is a protein complex consisting of red blood cells, which carry oxygen from the lungs to the tissues and is involved in the transport of carbon dioxide from tissues in the respiratory system. The hemoglobin is a simple protein (96%) of-globin and železosoderžaŝaâ nebelkovaâ Group (gems-4%). with a deficiency of hemoglobin (and hence oxygen) violated metabolic processes in cells tissues and organs. normal hemoglobin in the blood of men more than women (135-160 and 120-140 grams per litre of blood, respectively).

In certain diseases number of erythrocytes and hemoglobin content of not always vary together. There are diseases in which reduces the number of red blood cells, but increases the content of hemoglobin. And there are those in which both increases as the number of red blood cells and hemoglobin.

Higher amount of hemoglobin variant rules

High concentrations of hemoglobin in blood is characteristic of the inhabitants of the Highlands and mountain climbers. This reaction-organism adapts to the insufficient amount of oxygen contained in the air.

Some increase in haemoglobin can occur after physical activity or a walk in the fresh air.

Pernicious anemia

One of the reasons for increasing the number of hemoglobin in the blood may be a lack of vitamin B12 and folic acid. An example of such a disease is pernicious, or pernicious anemia (Addison-Biermer).

Pernicious anemia can occur against the backdrop of familial predisposition, if stomach diseases (atrophic gastritis-stomach mucous thinning and reduction of its secretory capacity) coupled with autoimmune (glitch immunity development of antibodies to their own cells, in particular, with the cells of the gastric mucosa) processes. All this reduces the possibility of malabsorption of vitamin B12. Particularly sensitive to vitamin B12 deficiency, bone marrow and nervous system tissue.

When anemia in humans is increased fatigue, drowsiness, loss of appetite, often pain in your mouth or tongue sensation (goose) in hands and feet. Man grows thin, broken gait, may experience blurred vision, and also violations of the reproductive organs.

The examination usually reveals a bright red “lacquered” language, paleness of skin, a small scleral and a number of neurological symptoms. When the laboratory study found a low of altered erythrocytes (red blood cells), with increased content of hemoglobin.

Pernicious anemia is treated with vitamin B12. With proper and timely treatment prognosis is favorable. But signs of nervous system lesions may persist if the patient was begun later than six months after the onset of the disease.
